    PLANNING AND NATURAL RESOURCES COMMITTEE R-19-140 October 22, 2019 AGENDA ITEM 2 AGENDA ITEM Addendum to the Mindego Hill Ranch Grazing Management Plan to Expand Conservation Grazing into the South Pasture GENERAL MANAGER’S RECOMMENDATION Forward a recommendation to the Board of Directors to adopt an addendum to the Mindego Hill Ranch Grazing Management Plan as an amendment to the Russian Ridge Use and Management Plan that adds the south pasture as part of the conservation grazing area on the property. SUMMARY The General Manager recommends adoption of an addendum to the Mindego Hill Ranch (Mindego) Grazing Management Plan (Grazing Plan) (Attachment 1) to expand the conservation grazing area within Russian Ridge Open Space Preserve (Russian Ridge). The addendum identifies the existing resources and current uses in the proposed south pasture expansion area, and provides recommendations for future improvements, management, and monitoring at the site. The recommendations include: installation of additional water infrastructure, updates to fencing, management of brush encroachment into grasslands, and monitoring of resource management activities. Midpeninsula Regional Open Space District (District) staff and the current grazing tenant have been working with the Natural Resources Conservation Service (NRCS) to secure cost-sharing support for the anticipated improvements. Implementation of the recommended infrastructure improvements is estimated to cost $119,341, of which approximately $85,000 is projected to be the District’s share with the remainder funded by the NRCS. Recommended improvements would span four years with work anticipated to begin in July 2020. If approved, the District’s share would be allocated across the next four fiscal years and requested as part of the annual Budget and Action Plan development process.

  • The Fault Line Threatening Dams
    The Fault Line Threatening Dams The Fault Line Threatening Dams Deficient structures, earthquake risks raise possibility of potentially catastrophic flooding By Jim Carlton June 24, 2017 FREMONT, Calif.-The coastal mountains that frame this working-class city next to San Francisco Bay harbor a hidden menace: a reservoir 10 miles away that sits next to an active earthquake fault, which experts say could cause a dam break and flood thousands of homes. The potential threat is so severe, the owner of the Calaveras Reservoir decided to build a replacement dam. But seven years after that work began, the dam is unfinished and isn't expected to be complete until 2019 -- four years behind schedule. The issues hampering the Calaveras Reservoir project show how difficult it can be to repair or replace an old dam, which is of growing concern nationally. An estimated 27,380 dams, or 30% of the 90,580 listed in the latest 2016 National Inventory of Dams, are rated as posing a high or significant hazard. Of those, more than 2,170 are considered deficient and in need of upgrading, according to a report by the American Society of Civil Engineers. The inventory by the U.S. Army Corps of Engineers doesn't break out which ones are deficient. But funding and inspection staffing are considered inadequate, the civil engineers' report said. An estimated $64 billion is needed to upgrade those dams, including $22 billion for those posing the highest hazard, according to the Association of State Dam Safety Officials, a nonprofit group in Lexington, Ky. "It's a huge problem with limited resources," said Ivan Wong, a consulting seismologist from Walnut Creek, Calif., who works on dam projects nationally.

Mapping Ghost Towns in the Santa Cruz Mountains GSP 510 Final Project BY: SARAH BREWER DECEMBER 2020 Abstract This project identifies areas of archaeological sensitivity for historic resources related to the segment of the South Pacific Coast Railroad that spanned from Los Gatos to Glenwood in the steep terrain of the Santa Cruz Mountains in Central California. The rail line was only in use for 60 years (1880-1940) until the completion of a major highway drew travelers to greater automobile use. During the construction and operation of the rail line, small towns sprouted at the railroad stops, most of which were abandoned along with the rail line in 1940. Some of these towns are now inundated by reservoirs. This project maps the abandoned rail line and “ghost towns” by using ArcGIS Pro (version 2.5.1) to digitize the railway, wagon roads, and structures shown on a georeferenced topographic quadrangle created in 1919 (Marshall et al., 1919).
